Thanks for documenting whats happening w the Robot, Jake.

robot repair

by Jake

omg i think i figured out what's wrong it's not throwing errors for servos 1 and 2 of the robot, it's referring to the two motors that are not connected, they were part of the assembly line. We actually have the controllers for both, they were in that huge metal box I put on the curb (after taking them out) but we only have one of the motors and anyway... on page 28 of http://servo-repair.com/documents/yaskawa/CACR-SR.pdf (labeled page 23 in the document) it shows the pins of the connector for the errors we're getting. I think if i short the right pins on the connectors, the errors will go away and it will think the two missing servo controllers are happy, even though we don't actually want to hook them up to anything. unfortunately, reconfiguring the ERC controller to know that it doesn't have two extra motors would require changing the EPROM, and even if we had a ROM burner handy I wouldn't know what to change. Does anyone want to play with the robot arm? -jake

robot encoder data format

by Jake

whoa... the encoders are serial? I guess there's a lot of stuff in there. the pinout is on page 26 but look on page 31: http://servo-repair.com/documents/yaskawa/CACR-SR.pdf apparently the encoders power on, and report their absolute position with a serial data packet, and then they switch over to quadrature to report movement pulses. Maybe this is why the pinout includes "battery" and there is supposed to be a battery to allow the encoders to "remember" where they were before? i guess if we fix the battery, and fix whatever loose wires are causing servos 1 and 2 to not pass tests, then it will probably work. ------ forwarded message ------- There are more Yaskawa documents here: http://servo-repair.com/documents.php The robot was made by Yaskawa which is now know as Motoman (subsidiary of Yaskawa). However, it seems like Yaskawa does not put any documentation about this on their website. I don't know who made the encoder but I think it might be Stegmann.

Fwd: [sfchalkboard] DEEP WEBSITE HELP

by Vicky Knox

Any takers? Here's the original post with contact info: https://lists.riseup.net/www/arc/sfchalkboard/2014-08/msg00002.html ---------- Forwarded message ---------- Date: 2014-08-01 12:56 GMT-07:00 Subject: [sfchalkboard] DEEP WEBSITE HELP To: sfchalkboard <sfchalkboard(a)lists.riseup.net> Hi Chalkeristas/istos-- HELP! I am an artist doing complicated social projects and I need a web presence that makes sense. For instance, I am starting an alternative credit rating bureau, starting with one experimental loan to one person. It feels important to have a good way to communicate about this. I am not sure where to start, what to ask or search for, or how to value it. I have a small amount of money from a grant to work with, and I'm happy to do a money thing or a trade thing, and I'd even just be happy to get some advice. Thanks a million! -- *+whatever it takes+* STRIKE DEBT BAY AREA http://strike-debt-bay-area.tumblr.com FEMINIST REPRODUCTION W/ 3-D PRINTER http://wemakemeteorsnotmoney.tumblr.com POETS' SECURITY FORCE www.poetsecurity.net

russia's insane internet controls

by Praveen Sinha

I don't normally post a lot of stuff on international tech politics to hackerspace lists, but I think it's worth generating a conversation around this. My friends from Russia have been describing Putin's insane environment of fearmongering and national media control and censorship. This article talks effectively a national walled garden. http://www.slate.com/blogs/future_tense/2014/08/01/russia_bans_dissident_bl… How do you fight this?

Anti-Eviction Mapping Project Zine [call for submissions]

by Vicky Knox

CALL FOR SUBMISSIONS!!! The AMP Zine deadline is August 18th by email or postmarked by August 15th! The Anti-Eviction Mapping Project is making a zine! The zine is part of the Narratives of Displacement project and aims to share individual and community stories, thoughts and feelings surrounding the gentrification of San Francisco and the Bay Area and the resulting flood of evictions. Reflections on home, community and displacement are welcome. Be creative! Entries can be as small as one word or a tiny doodle, and up to 800 words. Potential submission formats include: poem, short story, essay, thought, doodle, sketch, painting, comic, print, stamp, quote, joke, collage, pretty much anything you can or cannot think of. The zine is open to anyone who has something to express related to these issues, but we would especially love to see contributions from folks who have been personally impacted in one way or another by gentrification and/or displacement. Please specify if you would like to remain anonymous. Otherwise we would love to credit you for your work in the zine. We will not edit submissions, but we do have a particular political and artistic vision for the zine that some pieces may not fit into. However, our goal is to be as open and accessible as possible, especially as a platform for typically marginalized voices and stories. Questions and submissions can be sent to ampzine(a)riseup.net and/or Anti-Eviction Mapping Project, 558 Capp Street, SF, CA, 94110. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Some background on AMP, from our website: The Anti-Eviction Mapping Project is a data-visualization, data analysis, and digital storytelling collective documenting the dispossession of San Francisco Bay Area residents. The project seeks to de-isolate those displaced and act as a tool for collective resistance. We use maps and digital storytelling to make the often invisible processes of eviction, displacement and gentrification clearly seen. We have released multiple maps, including our: - Eviction Pledge Map, where you can look up an address to determine its eviction history, and pledge never to rent or buy from a landlord or speculator who has profited off of displacement. - Our Crowdsourced Map of Loss and Displacement, where you can share your story, photo, of video on a geolocation platform, and add to the map. - Time-lapse maps of Ellis Act Evictions and all No-Fault Evictions that have taken place since 1997. We have also mapped evictions of seniors and people with disabilities over the last three years, with information about the landlords and speculators who have displaced them. - Map of serial evictions. - Map of income inequality. - Map of no-fault evictions surrounding tech bus stops. - And more!
